Well the verdict is in, we were able to compare different chips on one of our 97 4WD powerstrokes. We went with the US gear, here is the difference
Stock 2000rpm 153hp at wheel
Stock 2500rpm 166hp at wheel
Stock 3000rpm 174hp at wheel
Stock tourque at 2000rpm was 395lbs tourque
US GEAR CHIP
US 2000rpm 232hp at wheel
US 2500rpm 239 at wheel
US 3000rpm 241 at wheel
US tourque at 2000rpm was 602.9 increase of 218 lbs tourque way beyond the figures that we thought.
Shifting pattern is almost perfect solid shifts.
We did some 0 to 60mph times on dyno stock and will compare over winter the difference.
